Schedule 1
What this tool helps you do
This plotter estimates how repeated semaglutide, tirzepatide, or retatrutide doses overlap over time.
It uses a one-compartment model with first-order absorption and lets you compare separate lines or view combined exposure.
How it works
Method
Turn schedules into dose events
Each schedule has a compound, dose, day offset, start week, end week, and frequency in days.
Those schedule settings are expanded into individual dose events across the selected graph duration.
Method
Calculate an amount-like signal over time
Each event is modeled with a Bateman-style curve using half-life, bioavailability, volume of distribution, and time-to-peak assumptions.
The displayed y-value is not raw concentration but a concentration-derived amount-like proxy, which is better treated as a relative exposure signal.
Formula or method
ke = ln(2) ÷ half-life
ka is solved from tmax and ke
If ka ≈ ke: amount proxy = F × dose × ka × t × exp(-ke × t)
Otherwise: concentration = F × dose × ka ÷ (Vd × (ka − ke)) × (e^(−ke×t) − e^(−ka×t))
Example
A schedule from week 1 to week 4 with a 7-day frequency creates dose events on days 0, 7, 14, and 21.
In compare mode, duplicate schedules stay as separate lines; in accumulate mode, their exposure is summed.
Assumptions and limitations
This is an educational visualization tool, not a validated clinical PK simulator.
It must not be used for dose equivalence, medication switching, or individualized treatment decisions.

FAQ
Not exactly. It shows an amount-like exposure proxy derived from a concentration model, which is best treated as a relative signal.
You can compare schedule patterns visually, but the chart is not a dose-equivalence calculator.
Yes. The page can serialize schedules into URL parameters so the exact setup can be shared.
